Ynamide-Mediated Thionoester and Dithioester Syntheses

, p. 6628 - 6631 (2020/09/02)
A novel ynamide-mediated synthesis of thionoesters and dithioesters is described. The selective addition reactions of various monothiocarboxylic acids with ynamide furnish α-thioacyloxyenamides, which undergo transesterification with nucleophilic -OH or -SH species to afford thionoesters and dithioesters, respectively. The broad substrate scope, mild reaction conditions, and excellent yields make this method an attractive synthetic approach to thionoesters and dithioesters.
The Dual Reactivity of 5-S/5-O-Phenyl-1,4,2-oxathiazoles: A Fragmentation Pathway That Affords Nitriles in the Presence of Water
Lim, Yi Wee,Hewitt, Russell J.,Burkett, Brendan A.
, p. 4840 - 4842 (2015/08/03)
The rearrangement of substituted 1,4,2-oxathiazoles to nitriles in the presence of water is described. Preliminary investigations suggest that the reaction pathway proceeds via a 1,4,2-oxathiazolium intermediate, followed by trapping with water and subsequent decomposition to products. An unprecedented rearrangement of 5-phenyl-1,4,2-oxathiazoles bearing a C5 leaving group to nitriles in the presence of water is described.

The first systematic study of the thermal rearrangement/fragmentation of 5,5-disubstituted 1,4,2-oxathiazoles into isothiocyanates is reported. Structure-activity relationships reveal that the choice of substituent at the 5-position of the 1,4,2-oxathiazoles is the predominant factor to influence the ease of fragmentation.

(matrix presented) The reaction of carboxylic acids (1) with a variety of thiols or alcohols in the presence of phosphorus pentasulfide (P4S10) as a catalyst and reagent (20-40 mol %) proceeded effectively to afford the corresponding dithiocarboxylic esters (2) in high yields.
Kinetics and mechanism of the aminolysis of phenyl dithiobenzoates
Oh, Hyuck Keun,Shin, Chul Ho,Lee, Ikchoon
, p. 1169 - 1174 (2007/10/02)
The kinetics and mechanism of the reactions of phenyl dithiobenzoates with anilines in acetonitrile at 55.0 deg C have been studied.The large magnitude of βx(βnuc) and the signs of cross-interaction constants, ρeXY > 0, ρYZ XZ > 0, are all consistent with the carbonyl addition mechanism in which the breakdown of the tetrahedral intermediate, T+/-, is rate limiting.The thiocarbonyl group (C=S) is found to favour amine expulsion in contrast to the carbonyl group (C=O) which favours the S-bonded nucleofuge expulsion from T+/-.The signs of cross-interaction constants, ρXY, ρYZ and/or ρXZ, are shown to provide useful mechanistic criteria for distinguishing, especially, the carbonyl addition mechanism involving the rate-limiting breakdown of the tetrahedral intermediate (T+/- from the concerted SN2 mechanism.
Polyvalent Iodine in Synthesis; 3. An Efficient Method for the Synthesis of Aryl Arenedithiocarboxylates
Chen, Zhen-Chu,Jin, You-Yuan,Yang, Rui-Yang
, p. 723 - 724 (2007/10/02)
A new method for the synthesis of aryl arenedithiocarboxylates consists of the S-arylation of sodium arenedithiocarboxylates with diaryliodonium chlorides or bromides in tert-butyl alcohol.
A New Rapid Synthesis of Phenyl Dithiocarboxylates
Beslin, Pierre,Dlubala, Alain,Levesque, Guy
, p. 835 - 837 (2007/10/02)
The otherwise difficultly accessible phenyl dithiocarboxylates are prepared in good yields by the reaction of S-phenyl carbonochloridothioate with halomagnesium or sodium dithiocarboxylates.
